Everyone has their own particular way I suppose, this is what I've been doing for the past 12 months with 100% success rate(I'd always used clonex with great success in the past too, exact same method without the soak stage, it's all about the environment in my opinion), some take longer than others, but I usually get my 1st roots around 8 days, most are through by 12 and the stragglers may take 14 -18, but these are usually insurance/excess anyway and become mulch. It's fairly simple and inexpensive if you keep aloe plants.
Method:
Soak cuts immediately in fresh aloe/clean water 1-2hrs,
dip end of cut into end fresh cut aloe leaf,
poke cutting into (pre aloe/water soaked) root riot cube (I use some of the powdered stuff in the soak too)
place in propagator, spray 1-2 times per day with aloe/water
make sure plugs not too wet or too dry (spray if necessary)
Potted up some 11 day old clones last night, treated with 2 diff types of myco (I have always used great white, until some recent good advise)
